Description

Technical Field

[0001] The utility model relates to the field of welding tooling, in particular to a T-shaped steel pipe bracket welding tooling. Background Art

[0002] In five-axis equipment, a T-shaped steel tube serves as a support structure. Its structure is composed of two cut round tubes spliced ​​together. Two steel rings are embedded on either side of the inner tube to serve as bearing connections. To prevent the steel rings from falling off during use, spot welding is required on one side of each ring. However, the welding process can easily cause the rings to deform, affecting concentricity and positioning, and increasing manufacturing difficulties.

[0003] In existing welding tools, some are designed to retain machining allowances during use. The circular ring is welded first, then left to rest for a period of time to release stress at the weld point before machining the inner ring. However, the asymmetric shape of the T-tube often causes machine tool vibration, turning the circular shape inside the steel ring into an ellipse, ultimately increasing machining costs and difficulty. Furthermore, manual positioning welding also struggles to meet stringent positioning requirements. Therefore, to address these issues, a welding tool for a T-shaped steel tube bracket is proposed. Utility Model Content

[0004] The purpose of the utility model is to solve the shortcomings of the existing technology and propose a T-shaped steel pipe bracket welding tool, which aims to improve the problems of inaccurate positioning and inconvenient operation of the T-shaped steel pipe welding tool in the existing technology during welding.

[0005] To achieve the above-mentioned purpose, the utility model provides the following technical solutions: a T-shaped steel pipe bracket welding tool, comprising a transverse support shaft, the front side of the transverse support shaft is detachably connected to the longitudinal support shaft, the front side of the transverse support shaft is threadedly connected to a fixing assembly, the left and right sides of the transverse support shaft and the front side of the longitudinal support shaft are threadedly connected to joints, the outer sleeve of the joint is provided with a retaining ring, the outer side of the transverse support shaft is provided with a plurality of limit grooves, the inner sliding connection of the limit groove is provided with an inner limit block 1, the outer sliding connection of the inner limit block 1 is provided with an inner limit block 2, the outer fixed sliding connection of the transverse support shaft is provided with a plurality of outer limit blocks, the outer sleeve of the transverse support shaft is provided with two steel rings, the outer sliding connection of the transverse support shaft is provided with a T-tube transverse tube 1, and the front side of the T-tube transverse tube 1 is fixedly connected with a T-tube vertical tube 2.

[0008] As a further description of the above technical solution:

[0009] The inside of the steel ring contacts the outside of the second inner limit block, and the outside of the steel ring contacts the outside of the outer limit block.

[0011] The outer portion of the locking stud is slidably connected to the inner portion of the longitudinal support shaft, and the outer portion of the locking stud is threadedly connected to the front side of the transverse support shaft.

[0012] As a further description of the above technical solution:

[0013] A washer is sleeved on the outside of the locking stud, and the outside of the washer is slidably connected to the inside of the longitudinal support shaft.

[0014] As a further description of the above technical solution:

[0020] The utility model has the following beneficial effects:

[0021] 1. In the present invention, the T-shaped steel pipe bracket welding fixture accurately positions the steel ring on the horizontal support shaft through the cooperation of the inner limit block 1, the inner limit block 2 and the outer limit block, laying a solid foundation for subsequent welding work. During the installation stage of the T-tube component, the relative position of the steel ring and the T-tube cross tube 1 is determined based on one side as a reference, ensuring the accurate position of the T-tube cross tube 1 during the welding process.

[0031] The following will be combined with the drawings in the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. Obviously, the embodiments described are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without making creative efforts are within the scope of protection of the present invention.

[0032] Reference Figures 3 to 5As shown, the present invention provides an embodiment of a T-shaped steel pipe bracket welding tool, including a transverse support shaft 1. The transverse support shaft 1 serves as the main transverse support structure of the entire tool, and can provide solid support for other components. The front side of the transverse support shaft 1 is detachably connected to a longitudinal support shaft 2, which can work in conjunction with the transverse support shaft 1 to provide longitudinal support for the welding of the T-shaped steel pipe bracket.

[0033] The front side of the transverse support shaft 1 is threadedly connected to a mounting assembly for fixing, and the mounting assembly includes two fixing grooves 3, which serve as the installation position of the locking stud 4, and its connection performance is stable and reliable. The outside of the fixing groove 3 is opened on the front side of the transverse support shaft 1 to ensure that the position of the fixing groove 3 is accurate. The inside of the fixing groove 3 is threadedly connected to a locking stud 4, which can firmly connect the transverse support shaft 1 and the longitudinal support shaft 2 together, and its connection performance is stable and reliable. The outside of the locking stud 4 is slidably connected to the inside of the longitudinal support shaft 2 to ensure that the locking stud 4 is stably installed. The outside of the locking stud 4 is threadedly connected to the front side of the transverse support shaft 1, so that the locking stud 4 can effectively fix the transverse support shaft 1 and the longitudinal support shaft 2;

[0034] The left and right sides of the transverse support shaft 1 and the front side of the longitudinal support shaft 2 are both threadedly connected to connectors 5, which can provide a connection interface for other components and its connection performance is stable and reliable. The outer sleeve of the connector 5 is provided with a retaining ring 6, which can limit and protect the connector 5.

[0035] Reference Figures 1 to 3 As shown, the exterior of the transverse support shaft 1 is provided with a plurality of limit slots 7, which provide locations for the installation of inner limit blocks 1 8, inner limit blocks 2 9, and outer limit blocks 10. Their positions and dimensions are rationally designed. The interior of the limit slots 7 is slidably connected to inner limit blocks 1 8, which can slide within the limit slots 7 to provide support for the positioning of the steel ring 11. The exterior of the inner limit block 1 8 is slidably connected to inner limit block 2 9, which can work in conjunction with inner limit block 1 8 to further improve the positioning accuracy of the steel ring 11.

[0036] The outer portion of inner limit block 1 (8) slides inside the transverse support shaft (1), ensuring stable and reliable operation of inner limit block 1. The outer portion of inner limit block 2 (9) slides inside the transverse support shaft (1), enabling inner limit block 2 (9) to work in conjunction with the transverse support shaft (1). The outer portion of inner limit block 2 (9) slides inside the limit slot (7), ensuring accurate installation of inner limit block 2 (9).

[0037] The interior of the T-tube riser 13 slides onto the exterior of the longitudinal support shaft 2, ensuring stable installation. Multiple external limit blocks 10 are fixedly and slidingly connected to the exterior of the transverse support shaft 1. These blocks work in conjunction with internal limit blocks 1 (8) and 2 (9) to improve the positioning accuracy of the steel ring 11. The rectangular shape of the external limit blocks 10 effectively limits the position of the steel ring 11. The elongated shape of the internal limit block 1 (8) facilitates better coordination with the other limit blocks.

[0038] Reference Figure 2 and Figure 6 As shown, the outer portion of the transverse support shaft 1 is sleeved with two steel rings 11. The steel rings 11 are key components for welding. The inner portion of the steel rings 11 contacts the outer portion of the inner stop block 9, and can work in conjunction with the inner stop block 9 to improve positioning accuracy. The outer portion of the steel rings 11 contacts the outer portion of the outer stop block 10, ensuring the stability of the position of the steel rings 11.

[0039] The outside of the transverse support shaft 1 is slidably connected to a T-tube cross tube 12, which is part of the T-shaped steel tube bracket. The front side of the T-tube cross tube 12 is fixedly connected to a T-tube vertical tube 2 13 to ensure that the connection between the T-tube cross tube 12 and the T-tube vertical tube 2 13 is firm.

[0040] The outer sleeve of the locking stud 4 is provided with a washer 14, which can play a protective role. The outer portion of the washer 14 is slidably connected to the inner portion of the longitudinal support shaft 2 to ensure that the washer 14 is installed stably.

[0041] Working Principle: First, the welding fixture's main structure consists of a transverse support shaft 1 and a longitudinal support shaft 2. Transverse support shaft 1 is provided with a fixing slot 3, secured by a locking stud 4 and a washer 14. Joints 5 and retaining rings 6 serve as connections and limiters. Limit slots 7 accommodate inner limit blocks 1 8, inner limit blocks 2 9, and outer limit blocks 10. Steel rings 11 provide specific connections and assist in the welding process.

[0042] Working stage of the steel ring 11 positioning device: First, the two steel rings 11 are placed on the transverse support shaft 1, and the transverse support shaft 1 and the longitudinal support shaft 2 are locked using the inner limit block 1 8, the inner limit block 2 9 and the outer limit block 10 to ensure that the position of the steel ring 11 on the transverse support shaft 1 is stable. The coordinated use of these limit blocks allows the steel ring 11 to be accurately positioned in the required position, laying the foundation for subsequent welding work.

[0043] During the T-tube assembly phase, insert the T-tube cross tube 12 into the horizontal support shaft 1 in the correct direction, and use one side as a reference to determine the relative position of the steel ring 11 and the T-tube cross tube 12. This ensures that the position of the T-tube cross tube 12 is accurate during welding, improving welding accuracy.

[0044] Next, install the longitudinal support shaft 2 and insert the longitudinal T-tube riser 2 13 into the longitudinal support shaft 2. At this point, the structure of the entire T-shaped steel pipe bracket is initially formed, and the support and positioning of the transverse support shaft 1 and the longitudinal support shaft 2 ensure that the position of each component is accurate and stable.

[0045] During the heating system's operation phase, hot water is pumped through the tooling's internal waterways, evenly heating the tooling. Utilizing the principle of thermal expansion and contraction, the gap between the outer T-tube cross tube 12 and the inner steel ring 11 decreases as the temperature rises, eventually closing completely. This heating method tightens the weld joint, improving weld quality and strength.

[0046] Cooling and disassembly stage: After the two outer T-tube horizontal tubes 12 and T-tube vertical tubes 2 13 are completely welded to the steel ring 11, they are left for a period of time to release stress. The fixture is then allowed to cool. At this time, due to the reverse effect of thermal expansion and contraction, the connections between the various components will become slightly loose. First, remove the inner limit blocks 1 8 and 2 9. At this time, the outer limit block 10 can be removed. Then remove the support shaft and the fixture can be removed. This disassembly method is simple and convenient and will not damage the welded T-shaped steel tube bracket.

[0047] Finally, it should be noted that the above is only a preferred embodiment of the present invention and is not intended to limit the present invention. Although the present invention has been described in detail with reference to the aforementioned embodiments, those skilled in the art can still modify the technical solutions described in the aforementioned embodiments or make equivalent replacements for some of the technical features therein. Any modifications, equivalent replacements, improvements, etc. made within the spirit and principles of the present invention should be included in the scope of protection of the present invention.
